Squeeze Pin Technology in HPDC Scientific Control of Local Shrinkage Porosity In High Pressure Die Casting, porosity is one of the most common and costly rejection problems. However, every porosity defect is not the same. In many HPDC plants, shrinkage porosity is often treated like gas porosity, and because of this wrong diagnosis, teams spend time on unnecessary venting changes, vacuum trials, die corrections, process adjustments and repeated production trials without getting stable results. This recorded course is designed to help HPDC professionals understand squeeze pin technology in a clear, practical and scientific way. The main focus of this course is localized shrinkage porosity control, especially in thick sections, mounting bosses, pressure-tight areas, oil leakage zones, heavy wall sections and hotspot regions where normal intensification pressure is not able to work effectively after gate freeze. The course explains the complete logic of squeeze pin appl...;
